Application examples
The table below contains various applications together with the type and num-
ber of motor starters EM 300 that you need for each application. You can
actuate both pole-changing motors and motors with separate windings.
Notes
1) The two speeds must be mutually interlocked in the user program with the
feedback contactor of the other starter.
2) see 1), but in addition the output brake of one starter must remain set during
switchover and activation of the other starter.
3) This version is suitable if you want to loop the 24 V DC braking voltage
through to the next drive. The 24 V DC braking voltage cannot be looped
through via a motor starter without braking contact.
